Description

Technical Field

[0001] The utility model relates to the technical field of rubber bushing processing, in particular to a feeding device for an injection machine. Background Art

[0002] As a common automotive component, rubber bushings belong to automotive rubber products and are usually the hinge points between various parts of the vehicle body. They have excellent elasticity and attenuation characteristics, can withstand loads, isolate and attenuate vibrations, reduce noise, ensure ride comfort, and have an important impact on vehicle suspension design.

[0003] An injection molding machine is a primary molding device that uses plastic molding molds to create various shapes of plastic products from thermoplastics or thermosetting materials. Injection molding machines are commonly used in rubber bushing processing. To improve production efficiency, an injection molding machine is typically equipped with several mold cavities.

[0004] During the operation of an injection molding machine, a skeleton (typically a cylindrical metal part) must first be placed into each mold cavity. After loading, the rubber is heated to a molten state. High pressure is then applied to the molten rubber, causing it to be ejected, filling the mold cavity and coating the skeleton. After cooling, the rubber bushing is obtained. Currently, the loading process relies on manual labor, requiring the skeleton to be manually placed into each mold cavity. This is not only labor-intensive and inefficient, but also involves direct contact with the mold cavities, posing a significant risk. Utility Model Content

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Refer to Figure 1-3 , a feeding device for an injection molding machine, which includes a first panel 1 and a second panel 2 installed at the bottom of the first panel 1 through sliding fit. A number of first through holes (not shown in the figure, the same below) penetrating its upper and lower surfaces and a number of second through holes 3 are respectively provided on the first panel 1 and the second panel 2. The second panel 2 can be pushed and pulled along the length direction of the first panel 1. When the second panel 2 is pushed forward, a number of second through holes 3 respectively communicate with a number of first through holes one by one, forming a channel for the workpiece to fall; when the second panel 2 is pulled backward, a number of second through holes 3 are respectively misaligned with a number of first through holes, and the second panel 2 closes a number of second through holes 3 from the lower side.

[0020] In the present invention, a groove 4 extending along its length direction is provided on the lower surface of the first panel 1. Sliding grooves 5 extending along its length direction are provided on the left and right inner walls of the groove 4. Sliding strips 6 are fixedly connected to the left and right sides of the second panel 2, and the left and right sliding strips 6 can respectively slide back and forth along the left and right sliding grooves 5. Thus, the second panel 2 is installed at the bottom of the first panel 1 through sliding fit.

[0021] In the present invention, two strip-shaped grooves 7 penetrating its upper and lower surfaces are respectively provided on the rear side of the first panel 1. Two columns 8 are fixedly connected to the rear side of the upper surface of the second panel 2. The two columns 8 respectively pass through the two strip-shaped grooves 7 and extend out, and a cross bar 9 is fixedly connected to the extended ends of the two columns 8.

[0022] Thus, a U-shaped handle is formed by the two columns 8 and the cross bar 9. By holding the U-shaped handle and pushing and pulling along the two strip-shaped grooves 7, the second panel 2 can be conveniently pushed and pulled along the length direction of the first panel 1.

[0023] In the present invention, handles 10 (U-shaped) are fixedly connected to the left and right sides of the upper surface of the first panel 1, which are convenient for holding, and thus it is convenient to carry the entire feeding device.

[0024] In the present invention, a number of sleeves 11 are fixedly connected to the upper surface of the first panel 1. The number of sleeves 11 respectively corresponds to a number of first through holes one by one. Thus, it can both store the workpiece (skeleton) when the second panel 2 closes a number of second through holes 3 from the lower side, and provide guidance for the fall of the workpiece (skeleton).

[0025] In the present invention, positioning posts 12 are fixedly connected to the four corners of the lower surface of the first panel 1 .

[0026] Correspondingly, positioning holes are provided at the four corners of the upper surface of each mold cavity of the injection molding machine. Therefore, when the loading device of the present invention is placed on the injection molding machine, each positioning column can be inserted into each positioning hole accordingly. When the second panel 2 is pushed forward, several second through holes 3 are respectively connected with several first through holes to form a channel for the workpiece to fall, which can correspond to each mold cavity one by one.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] When in use, first pull the second panel 2 back, and the several second through holes 3 will be offset with the several first through holes respectively. The second panel 2 will close the several second through holes 3 from the bottom side, and then the several workpieces (skeletons) will be placed in the several sleeves 11 respectively for storage, so as to realize the pre-storage of workpieces (skeletons).

[0029] Next, the loading device of the present invention is carried to the injection molding machine so that each positioning pin is inserted into each positioning hole. At this time, the plurality of second through holes 3 respectively correspond to each mold cavity of the injection molding machine.

[0030] Then, the second panel 2 is pushed forward, and several second through holes 3 are respectively connected with several first through holes to form a channel for the workpiece to fall. Each workpiece (skeleton) falls into each mold cavity accordingly, thereby realizing the delivery of the workpiece (skeleton) into each mold cavity of the injection molding machine, that is, realizing one-time centralized loading.

[0031] Then, the feeding device of the utility model is removed, the injection molding machine is started, and the rubber bushing is manufactured according to conventional processing procedures.

[0032] It should be noted that since the operator does not need to directly contact the mold cavities during the loading process, the operational safety is improved.

[0033] In addition, for one injection molding machine, it is usually necessary to adopt at least two loading devices of the present invention, which can be used alternately to further improve work efficiency.

[0034] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0035] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent modifications made according to the scope of the claims of the present application are within the scope of protection of the claims of the present application.
